My way of rating would be
Presentation: It would include all art style, graphics, sound effects, music, voice acting, menus, and anything of the sort.
Story: It would include if the story is any good, how it was told, hidden secrets, discoverys, sidequest, originality and so on.
Performance: Gameplay mecanics, glitches and buugs, framerate, longetivity,
This would be a negativity now but
Content:
Like some games now want to sell you a game by pieces and while not included in the total score, this will be things that cn go in the negative and deduct points. lIKE if the story is to short, micro transactions, day one dlc that could have obvioulsy been included for free doesent matter if its cosmetic like evolve, deductions are necesary. Super expensive season passes, and you get where im going with this.
Obvious I want an average of the 3. Even if reviewers fake it for clicks we would know. Like a game like call of duty should recive praise for its gameplay but punish for its story. The order praise for its presentation but punish for gameplay. Evolve praised for gamplay but punished for content and story.
This would crete a lot of games in the 70's wich ishould be a good game, A few in the 80's that should be great games, and just a rare couple in the 90's that are true gems.
